Popis: | Three-hundred Angus cows were used in a randomized design to evaluate trace mineral supplementation over a 209-d trial on cow and calf performance, liver trace mineral content, and immune function. Treatments included the following supplemental trace minerals: 1) inorganic trace minerals—low level; 2) inorganic trace minerals—high level; and 3) organic trace minerals—high level. Cows fed the high level of inorganic trace minerals lost more weight (P |
